1,043,526. spcimen of, mers ment Patented Nov. 5', 1912. y Application mea April a2, 190e. serial mi. 428,542.

To au wma may mem; the; eatin 2o, (1f-Said barge 17, and Said sa Be it known that I, ROBERT H. L1nnAi.,-'of Gloucester City, in the' county of Camden and State of New Jersey, have invented a. 5 certain new and useful l,Improvement fin Telephones,` whereof the following lis 'a specification, reference being had to the ac companying drawings.

My improvement 1s particularly` applica- My invention comprises the various novel hereinafter more denitely s ecitied.

In the drawings; Figure ,is aside elevation of a tug o eratively connected with a lbarge andl e bodying my improvement. Fig. II, is a fragmentary-perspective view of an end of the hawser which forms the tow line between said vessels.

Referring to Fig. I; the tu hull 1, is provided with an exterior metal ic plate 2, permanentlyconnected with the battery 3, and telephone set 4, which latter is conveniently located in the pilot house 5. v

The flexible line conductor 6, is detachably electrically connected at one end with said telephone set 4, at the pilot house, and, at its opposite end with the terminal 7, carried by the hawser 8. As indicated, in Fig. II, said terminal 7, is securely clam ed upon theend of the hawser 8, by the bo ts 49., and is electrically connected with the end of. the line conductor 10, which4 extends 'through said hawser-to theterminal 14, at the oppo site end thereof, which.` is similar to the terminal 7, above described. Said conductor 10, is preferably s irally laid in said 'hawser so as to be capa leof extension under the strain'to which xthehawser is .subjected, and without 'disturbing its electrical connection with said terminals 7 and 14.

electrically connected, 'byf the flexible line conductor 1,8, with the telephone set 19, in;

ble to telephone circuits adapted ,r'orinterfeatures of construction and arrangement '19, -is permanently connected through the battery 2 1, with the. metallic plate 22, upon the exterior of the hull of Isaid' barge 17.

Therefore,*it is to be understood that when the two vessels are .connected as above described, 'an electric tele hone circuit is established, upon lone si e through the line carried by the hawser 8, and upon the other 'side'through the water 23, supporting said vessels.

lI do not -desirevto limit myself to the prel .i

cise details of construction and arrangementl above described, as 1t is obvious that various modifications may be madetherem without departingl from the essential feaas defined the apmovement; of a telephone conductor extending spirally in .saidi hawser; electric terminals carriedbysaid hawser, comprising connecting means for said conductor; tele- 4.phone sets respectively supported by said marine vessels and detac ably connected withlsaid terminals, including means upon each of. said vessels in electrical connection withthe water supporting them.

2. The combination with a hawser connecti'ng two'relatively movable marine vessels and -limiting the `range of their relative movement; of a telephoneconductor extend` ing in said hawser; electric terminals carried by said hawser,. comprising connecting means for saidcon'ductor; telephone sets r e spectively supported by said marine. vessels and detachably connected with said terminals, including means upon each of said lvessels in electrical connection with the water supporting them'.

3. The combination with a hawser connecting two relatively movable marine vesL sels and limiting the range of their relative movement; of-'a telephone conductor extending spirally in said hawser; electric terminals vcarried by said hawser, comprising connecting means forsaid conductor; and, telephone sets respectively supported by sald marine vessels and detachably connected with said terminals.

terminals; whereby limited relative move-y ment of said sets, and limited extension and contraction of said hawser is permitted without breaking the telephone circuit.

6. The combination with a havvser; of a telephone conductor extending in said hawser; electric terminals carried by said havv-v ser comprising connecting means for said conductor; and, `telephone sets respectively detachably connected with said terminals; whereby limited relative movement of said sets, and limited extension and contraction of said havvser is permitted Without breaking the telephone circuit.

7. The combination with a hawser; of an electric conductor extending spirally in said Vhavvser; and, electric terminals carried by said hawser comprising connecting means for said conductor; whereby limited extenslon and contractlon of said hawser is permitted without breaking the electric circuit.

[SEAL] 8. The combination with telephoneY sets respectively supported by relatively movable marine vessels; of a hawser connecting said vessels, limiting their relative movement, and, means extending in said hawser, electrically connecting said sets in operative relation.

9. The combination with telephone sets respectively supported by relatively movable marine vessels; of a hawser mechanically connecting said vessels, limiting theirrelative movement; an electric conductorl permanently secured to and carried by said hawser; and, terminalspermanently secured to and carried by said hawser, at the respectively opposite ends thereof, permanently electrically connected with the respectlvely opposite ends o said conductor and havlngmeans arranged to detachably electrically connect said conductor with the respective telephone sets; whereb said permanently united havvser and con uctor form a single iiexible mechanical and electrical connector, Vwhich may be readily detached, attached, and coiled like an ordinary hawser. r

In testimony whereof I have hereunto signed my name at Port Richmond, N. Y., this 7 day of April, 1908.

ROBERT H. LINDAL.

It is hereby certitied that in Letters Patent No. 1,043,526, granted November 5, 1912, upon the application of Robert H. Lindal, of Gloucester City, New Jersey, for i an improvement in Te1ephones, 'an error appears in the printed specification requiring correction as follows: Page 2, line 4, for the Word conductors read cpnducto'r; and that the said Letters Patent should be read with this correction.

therein that the same may conform to the record of the'case inthe Patent Oce.
